Breathing Apparatus

Abstract

A breathing apparatus comprising: an inlet configured to receive pressurised gases, an outlet configured to diffuse the pressurised gases within the dead space of a face mask, a detachable nozzle manifold configured to pass the pressurised gases from the inlet to the outlet, and a seal configured to substantially air tight seal the nozzle manifold between a user's face and a bottom inner surface of the mask.

1 . A breathing apparatus comprising:
 an inlet configured to receive pressurised gases,   an outlet configured to diffuse the pressurised gases within the dead space of a face mask,   a detachable nozzle manifold configured to pass the pressurised gases from the inlet to the outlet, and   a seal configured to substantially air tight seal the nozzle manifold between a user's face and a bottom inner surface of the mask.   
     
     
         2 . The apparatus in  claim 1  further comprising a clip configured to substantially hold the detachable nozzle manifold in place on the mask. 
     
     
         3 . The apparatus in  claim 1  further comprising an adhesive layer configured to substantially hold the detachable nozzle manifold in place on the mask. 
     
     
         4 . The apparatus of  claim 1  further comprising a flexible conduit communicating the pressurised gases to the inlet. 
     
     
         5 . The apparatus of  claim 4  further comprising a quick release connector between the flexible conduit and the inlet. 
     
     
         6 . The apparatus of  claim 1  further comprising a filtered blower configured to deliver filtered pressurised air to the inlet. 
     
     
         7 . The apparatus of  claim 6  wherein the blower is variable speed configured to deliver 20-30 L/min. 
     
     
         8 . The apparatus of  claim 1  wherein the seal comprises a first elongated foam strip adhered to the side of the manifold configured to face the user, and a second elongated foam strip shorter than the first strip adhered to the side of the manifold configured to attach to the mask. 
     
     
         9 . The apparatus of  claim 1  wherein the mask is N95 certified disposable face mask.
